Abstract
Fractures of trapezium are reportedly rare, less than 5% of all carpal bones fractures. A vertical sagittal fracture type is encountered in about 20% of cases. This fracture type is unstable and is usually displaced like a Bennett's fracture. Open reduction and internal fixation is admitted to be the best method of treatment, but it has always been augmented with a postoperative cast immobilization to temporary stabilize the trapeziometacarpal joint. We describe a case of displaced vertical sagittal fracture of the trapezium with trapeziometacarpal subluxation treated by open reduction and internal fixation of the trapezial fracture, associated with temporary stabilization of the trapeziometacarpal joint using two percutaneous intermetacarpal Kirschner wires.
